In this paper, we compare the current spread of invasive populations of neophytes, the genus Fallopia Polygonaceae in town Hlohovec SW Slovakia in intensively farmed agricultural landscape after ten years. F. × bohemica has been the most successfully spreading hybrid. In 2001, it had colonized the area of 1 520 m2 on 54 localities and in 2011 by 120 % more 3 338 m2, 63 localities. The total surface area occupied by F. japonica was small.
